Scattered thunderstorms Saturday and Saturday evening

We start our Saturday with wafts of fog. A heavy fog warning is in effect for parts of northern Minnesota and Douglas County in Wisconsin through 10 a.m. Saturday:

chances of thunderstorms

Isolated showers and thunderstorms will linger over parts of Minnesota and western Wisconsin Saturday morning. We then expect a break in action for most areas, with isolated thunderstorms returning later on Saturday afternoon and Saturday evening.

In the late afternoon and evening isolated strong to violent thunderstorms are possible. The NWS Storm Prediction Center is showing a low risk of severe weather (shaded yellow) across much of central Minnesota and a portion of northern Minnesota today and tonight:

Low risk means isolated violent thunderstorms are possible. Isolated severe thunderstorms are possible later this afternoon or tonight in the darker green shaded areas, including the Twin Cities.

You can track showers and thunderstorms on the new interactive radar on MPR News’ weather page. You can pan and zoom the radar display on our website to see rain at your location, across Minnesota, western Wisconsin and beyond.

We have updated weather information for Minnesota and western Wisconsin on the Minnesota Public Radio News Network and the MPR News live weather blog.
